Contraction of "let go", used as an exclamation. Contrary to popular belief, this word was not invented by rappers. It appeared 50 years earlier, on page 45 of "Asterix the Gaul" in 1961. In the frame, A Roman soldier protests when Asterix grabs him by his (magically long) beard.

The most unintelligent way to say "Let's Go." Abbreviations are supposed to actually be shorter and easier to say than the original version. Not the same exact number of syllables. If you use this phrase other than to make fun of it, your IQ must be extremely low, or you must be trying entirely too hard to seem "cool." Please stop people. You sound stupid. Lego is a building block for children. Or the commonly kn own advertisement for Eggo waffles. The phrase "leggo" is just another example of a piece of shit that the rap community has given to popular culture. When rappers invented this word, they were thinking "Hmmmm, how fucking stupid can we sound?" And a bunch of idiots all over America fell for it. I am aware that this is not the real origin of the word, but that's besides the point. Point is, it's retarded; don't use it.

The southern way of saying "Let's Go" it's just like trying to say it 5x fast! More rappers are starting to use the term in their songs. (Plies), (Lil'Wayne), (Trey Songz) and (Young Jeezy) have all used it.
